Patented Oct. 1, 1929 UNITED STATES PATENT OFFICE MACHINE FOR REDUCINGRECORDS TO IGRAPHS Application filed May 28, 1828. Serial No. 280,987

My invention relates to machines for reducing records to graphs, andmore particularly to a machine into which a tabulated record can beplaced with a curve sheet, for

example, and onto which curve sheet said record can be represented as acurve or graph. Among the salient objects of my invention are: toprovide a machine in which the record sheet can be moved intermittentlya predeterznined distance, according to the record spacing thereon, andthe curve or graph sheet be also moved relatively, with indicating meansto assist the operator in making the proper movements, and with markingmeans movable with each adjustment to draw the graph as said markingmeans is moved; to provide in a machine of the character referred to,means for transferring the record to a reading position, whereby theoperator need not turn his head any considerable distance to view thedifferent records or indications which determine the movement of themarking means; and, in general, to provide a simple, practical, andaccurate mechanism for a quickly and accurately putting a record ingraph form, thus saving a great deal of time and reducing the chancesfor error to a minimum.

In order to explain my invention, I have 3 illustrated one practicalembodiment thereof on the accompanying two sheets of drawings, in whichis shown a machine particularly adapted for reducing to graph form thehourly and daily consumption of electric enorgy. In the drawings:

Figure I is a plan view of a machine embodying my invention, with partsbroken away to reduce the size of the figure;

Figure II is a front elevation thereof, with parts broken away andomitted;

Figure III is a vertical sectional view taken on line IIIIII of Fig. II;

Figure IV is a transverse sectional View taken on line IV-IV of Fig. I;

Figure V is a sectional view taken on line V-V of Fig. I and enlarged;and

Figure VI is a sectional view taken on line VI-VI of Fig. IV.

Referring now in detail to the drawings, 1 designates a longitudinalsupporting memher, provided with longitudinally spaced supportingbrackets 2 and 3, between which are supported two rollers 4 and 5, forreceiving and moving intermittently a record hearing sheet, designatedA, shown in Fig. I, with a part broken out. The roller 4, is supportedin U-shaped bearings 6, 6, in members 7, 7, extending upwardly from thebrackets 2 and 3, as will be seen in Fig. III, so as to rest upon andturn with the larger roller 5, for feeding the record sheet A. Theroller 5 is supported on a shaft 5, provided at one end with a hand nut8, for turning said roller, and at its other end said shaft is providedwith an operating lever .9, operating a dog 10, ona ratchet wheel 11,connected with the roller 5, whereby as said lever 9 is moved downwardlythe limit of its stroke, whichis determined by the toe 9' thereofengaging with a fixed part 12, turns said roller 5 a predetermineddistance, which is in the present instance the same as the spacesrepresenting hour periods on said record sheet A. Said lever 9, at itslower end is provided with a hub-like portion 13, turning looselyv onthe shaft 5, and having secured therein, with a pin 14, a shaft 15,having therein, longitudinally thereof, a key-way 15. The other end ofsaid shaft 15, is supported in a bracket 16, from the member 1, and hasslidabl} thereon a wheel 17.

Supported above the member 1, is a shaft 18, anchored at one end in abracket 19, on said member 1. Slidably mounted on said shaft or bar 18,is a sleeve 20, supporting thereunder a magnifying glass 21, and supporting above said glass a mirror 22, said parts being movable alongsaid bar 18, over the record sheet A, whereby a record on said sheet isenlarged by the magnifying glass 21, and reflected in the angular mirror22, and to a second mirror 23, supported in a bracket 24, on a collar25, moving along a ratchet bar 26, supported at one end in a bracket 27,on the member 1, the opposite end of said rack or ratchet bar 26, beingsupported at the end of said member 1, in a bracket 28. Set screws 27and 28' are used to hold said rack bar 26 in said brackets 27 and 28.

opposite sides. Secured to the front edge of the connecting plate ormember 31, Fig. 1V, is an underlying member 33, which underlies theratchet bar 26 an'd'turns up in front of the same and forms a supportfor two pulleys 34 and 35, the upturned portions of said member 33 beingdesignated 33, 33', asseen in Fig. V. An angle member 36 is mounted onthe plate member 31, and this carries a spool or sleeve 37 extendingover the ratchet bar 2 to which ispivotally mounted one end of a lever38, the other end of which'is pivotally connected with a pawl39, with apulley 40 mounted on the pivot connecting said is ver 38 and pawl 39, asclearly shown in F V. The free end of said pawl '39 engages with thenotches'of the ratchet bar 26, for.

a purpose hereinafter referred to. A second member or bracket41 isconnected with the "ertical plate or web 32, Fig. IV, and carries ascrew 42, operating through a part 43, with a knurled nut or head 44 onsaid screw for operating it, to increase or diminish the tension of aspring 45, under the lever 38, with its lower end seated upon a bracket46, attached to the plate '31. 'Thus said lever 38, and the pawl 39 arenormally raised and when the pulley 40 is moved downwardly with saidlever and pawl, the engagement of the pawl 39 on the ratchet bar 26,operates to move the carriage to the right, and this is accomplished ina manner to be described.

Connectedto the lever 9, which is operated to turn the rollers 4 and 5for feeding the record sheet A, is: a cable 47, which runs over a pulley48, on the bracket 3, and thence over another pulley 49, at right anglesto the pulley 48, said cable being connected to a coiled spring 50, withthe cable extension from the opposite end of the spring, as

shown in Fig. I, and passing thence under. pulley 34, Fig. V, up overpulley 40, and

down under pulley 35, and thence to an anchor bolt or member 51,provided with an adjustmentnut 52, outside of the member 28, as clearlyshown in Figs. I and V. Thus when the handlever 9 is operated, saidcable 47 is drawn to operate the'pulley 40 and lever 38 and pawl 39,'tomove the carriage 2931 along the ratchet bar 26.

Mounted on the vertical plate or member 32, are four pulleys, 53, 54,and 56, and a flexible scale or tape 57 runs around said pulleys, asshown in Figs. I, V and VI, one end of which is attached to a carrierframe. 58, sliding on the two parallel members 29, 29, said scale beingattached by means of a set screw 59, on top of said carrier frame 56,while the opposite end of said scale 57 is secured to a cable 60,extended around a pulley 61, in the plate 30, and back to the carrierframe 58, to the rear of which said cable is attached, as at 62. Asupporting wheel 63fis'mountedohftlhe member;':"30,'at the extreme endof "said arri'age members 29-29. Said carrier frame 58, is provided withmeans-for supportinga pen or pencil, as at 7 64, for leaving a markalong the course of its movement -uponi'a curve or graph sheet B, onboard C.

Apoint-er S5 is'moifnted on the plate member 31 ,and extends up overthescale or graduated tape '5 7,fla swill be clear from Figs. 1, V and IV.it Z I' Y It will be notedthatthe'recordsheet A has the mirror 22 andthe imagnifyi ng glass 21 adjusted over a record in'tlie hour spaces. It1- briefly described as follows;

The record sheet'A i s putinto place, and.

.the mirror 22 and '21, being moved together are moved to overlie theparticular line or record ,which it is desired to represent on" thecurve or "graph sheet B, which'ha's been put in place'on the boardC,unde'r the memers 2929. Assuming that the first space on the sheet Ais under the glass and mirror and is reflected to the mirror'23, theoperator then moves the lever 9 one throw, which moves the recordfshee'tA one hour space. At the same time the cable47 has been operated tooperate the pulley 40:, lever '38 and pawl 39, which operates to.movethe carriage along the ratchet bar 26. The operator then moves thepen and its frame again to bring the correspondingnumb'er on scale 57 tothe one now seen in mirror: 23.1 The movement of the carriage along thebar 26 makes the short marks longitudinally of the sheet B, while themovement of the carrier frame 58 and pen or pencil makes the longermarks transversely of said sheet B, as illustrated by the marks M. Therecord is presumably read every hour and the hours record is transferredor repre sented by the movement of the carrier frame 58 and the pen 64in the two directions back and forth, at right angles. The spaces on thesheets Aand Bare arranged to indicate each an hour of time. There wouldbe, therefore, one sheet B per month used for any one line of record on30 or 31 A sheets.

Thus I have provided a machine in which the record sheet and the graphsheet can be placed, with means for moving the record sheet a.predetermined distance with each operation of the machine, and with amarking means mounted to be moved over the fixed graph sheet a distancedetermined by the particuiar record in view on the record sheet. I havealso provided a pyrosoope for conveniently reflecting the particularrecord which is to be the determining factor for the next move of themarking means. This avoids the necessity of glancing from one record tothe other with the almost certain probability of making errors inturning from one position to another. The inveniton makes it possiblefor one to quickly and accurately reduce a line of record from therecord sheet A to a graph on sheet B, and while I have shown anddescribed but one embodiment of the invention, I am aware that changescan be made in the details of construction and arrangement withoutdeparting from the spirit thereof, and I do not, therefore, limit theinvention to the showing made for explanatory purposes, except as I maybe limited by the hereto appended claims.
